Every audio file carries technical details you cannot see just by looking at the file name, things like its exact duration, bitrate, sample rate, and format. The Audio Metadata Viewer on File Tools Online reads that technical information straight out of your file and reports it back to you clearly, so you can check exactly what you are working with before you use, share, or upload it. There is nothing to install and nothing to configure, you upload a file and get a straightforward report of its real technical properties. It works the same way whether you are checking a single track or spot-checking a handful of files from different sources.
Open the Audio Metadata Viewer and choose the file you want to inspect. Drag and drop it, or select it from your device.
The tool reads the file's technical details automatically. There is nothing to configure or select.
Get a clear report of your file's duration, bitrate, sample rate, channels, and format.
The whole process typically takes just a few seconds. You are not changing your file in any way, this tool only reads and reports what is already there, so your original audio stays exactly as it was.
Check duration, bitrate, sample rate, channels, and format straight from the file itself.
Upload your file and get a report back in seconds, no manual digging through file properties.
The Metadata Viewer runs in your browser. There is no desktop app or plugin to download and keep updated.
Check an audio file's metadata from a laptop, desktop, or phone using nothing more than a web browser.
Your file is processed over HTTPS and automatically deleted from our servers within 30 minutes.
Checking your file's metadata does not cost anything, and nothing about your original file is changed.
The word metadata covers a couple of different things, and it helps to know which one you actually need. This tool focuses on technical metadata, the properties baked into the audio stream itself: duration, bitrate, sample rate, number of channels, and file format or codec. This is the kind of information that tells you what a file actually is, regardless of what it is named or labeled.
There is also tag metadata, things like song title, artist, album name, genre, or cover art, the kind of information you see in a music player's library view. This tool reads and reports technical file properties. It does not add, edit, or fix song title, artist, album, or other tag information. Both kinds of information are commonly called "metadata," which is exactly why the two get mixed up so often, but they live in different parts of a file and serve different purposes.
Checking a file's real technical details is useful any time you cannot simply trust a file name, a label, or what someone told you about a recording. These are the situations people run into most.
No. This is a common point of confusion, since "metadata" gets used for both technical file properties and the song title, artist, album, and cover art tags you see in a music library. This tool reads and reports the technical side, duration, bitrate, sample rate, channels, and format. It does not add, edit, fix, or look up song title, artist, album name, genre, or cover art, and it does not connect to any online music database to find missing tags for you.
If what you actually need is to add or fix the title, artist, or album information stored in a file, that is a tag editing job, which is a different tool than this one. It is worth checking that distinction before you upload a file here, so you get the report you actually need on the first try.
Checking a file's real technical properties usually means installing a dedicated media info program or digging through a media player's file properties dialog. The Audio Metadata Viewer on File Tools Online skips both. There is nothing to install and nothing to dig through. You upload a file, and the report appears automatically. For a quick check on one or two files, that is faster than opening dedicated software.
The tool accepts common audio formats such as MP3 and WAV, so in most cases you can upload a file directly and get a report without converting it first. If your file is in a less common or older format, run it through the Audio Converter first, then check the result.
The report focuses on a handful of core fields. Here is what each one actually tells you.
Because the Audio Metadata Viewer runs in your browser rather than as installed software, it works the same way on Windows, Mac, Chromebook, Android, and iPhone. There is nothing tied to one operating system, so you can check a file's technical details on whichever device you happen to have it on.
Audio metadata is information about an audio file rather than the sound itself. This tool focuses on technical metadata, such as duration, bitrate, sample rate, channels, and format.
No. This tool reads and reports technical file properties. It does not add, edit, or fix song title, artist, album, genre, or cover art tags.
The report covers duration, bitrate, sample rate, number of channels, and file format or codec, the technical properties of the audio stream itself.
Upload the MP3 to the Audio Metadata Viewer. The bitrate is reported automatically along with the file's other technical details.
WAV files can carry some metadata through optional chunks in the file format, but support is less consistent and less standardized than the tagging systems used by formats like MP3. Technical details such as duration, sample rate, and channels are always readable regardless of format.
Yes. Upload your file to the Audio Metadata Viewer and it will report the technical details automatically.
Technical metadata tells you what a file actually is, its real bitrate, sample rate, duration, and format, rather than what a label or file name claims. That matters when you are checking quality, troubleshooting playback, or confirming a file meets a specific requirement.
Yes. Upload your file and the tool reports its technical details automatically. There is no cost to use it.
Technical metadata describes the audio stream itself, duration, bitrate, sample rate, channels, and format. Tag metadata is descriptive information such as song title, artist, album, and genre, the kind you see in a music library. This tool covers technical metadata only.
No. This tool only reads and reports what is already in the file. It does not modify, fix, or repair the file or its metadata in any way.
The tool accepts common audio formats such as MP3 and WAV. If your file is in a less common format, convert it first with the Audio Converter, then check the result.
Yes. The tool runs in your browser, so it works the same way on Windows, Mac, Android, and iPhone without installing anything.
File Tools Online is a collection of free, browser based tools for working with audio, video, PDF, and image files, built for people who need a quick, reliable result without installing software. The Audio Metadata Viewer is one part of a larger set of audio tools, so once you know a file's real technical details, you can trim it, convert it, normalize it, or equalize it without leaving your browser.
File names and labels do not always tell the truth about what is actually inside a file. Reading the real technical metadata is the fastest way to know exactly what you are working with, whether you are checking quality, troubleshooting a playback issue, or confirming a file meets a specific requirement.
